Specification of Letters Patent.
Patented June 6, 1916.
Application filed September 28, 1915; Serial No. 53,153.
To all whom it may concern:
Be it known that I, FREDRICK W. BECKER, a citizen of the United States, residing at lVashington, in the District of Columbia, have invented certain new and useful 1mprovements in Mufllers, of which-the following is a specification.
This invention relates to an improved inufiier and the principal object of the invention is to provide a mufiler with an improved type of battle plates so constructed and assembled as to eliminate back pressure and prevent noise.
Another object of the invention is to so construct the battle plates that a small portion of the gases may pass directly through the plates when striking the same, the greater portion of the gases being retarded and caused to take a tortuous course through the mufiier.
Another object ofthe invention 1s to so mount the bafile plates as to permit of easy removal from the casing when cleaning the muflier.
"This invention is illustrated in the accompanying drawings, wherein Figure 1 is a view in longitudinal sect on through the mufller, Fig. 2 is a view showing the muffler in end elevation, and Fig. 3 through 12 are views in elevation of the battle plates which are shown in Fig. 1.
This muflier is provided with a cylindrical casing -10 which may be of any suitable length and diameter and has its ends closed by the caps 11 and 12, the inlet pipe 13 being connected with the cap 12 and the outlet pipe 14 leading from cap 11. These pipes 13 and 14 may be removably connected with the caps 11 and 12 in any suitable manner, but for the purpose of illustration, they have been shown screwed into the enlargements 15 and secured by the locking nuts 16.
Within the casing 10 there is provided the bafiie plates 17, 18, i9, 20, 21, 22, 23, 24, 25 and 26 each of which is provided to one side of the center with a relatively large opening 27 through which the greater ortion of the gases will pass as they trave through the mullier. It should be noted that these openings are positioned in staggered relation as shown in Fig. 1 and therefore the gases will be guided through the casing in a tortuous course. The 0 posite side portions of the first eight ba e plates are provided with 5 relatively small openings 28, which are preferably arranged as shown in Figs. 3 through 10 but which may be grouped in any other manner if desired. It should be noted, however, that the openings 28 decrease in number from plate 17 to plate 24, this being an essential feature of the invention as will be hereinafter brought out in the description of the operation. The last two plates 25 and 26 are not provided with openings 28 as these two plates do not require them.
In assembling this muflier the casing 10 is cut the proper length and after tongues 29 of the baffle plates are bent as shown, the plates are put in place as shown in Fig. l and secured by the removable fasteners 30. The caps 11 and 12 are now put in place and the securing bolts 31' which pass through the openings 32 in the baflle plates and assist in holding the plates in the proper position are put in place and tightened thus securely holding the caps upon the casing in tight engagement therewith. It is obvious that if desired one cap and the bolts can be first put in place and the baflie plates then slipped into the casing upon the bolts thus causing the plates to pass into the casing in the proper position to permit the removable fasteners to engage the tongues 29.
When the mufiler is in use the gases from the engine enter the casing through the pipe 13 and strike that portion of the plate 17 having the small openings formed therein. A portion of the gases will pass through the small openings but most of the gases will move across the casing and ass through the large opening 27 of plate 1* and strike plate 18. This plate is provided with a fewer number of small openings than plate 17 and while they will permit a portion of the gases to pass directly through the plate, a larger proportion of the gases will pass across the casing and pass through the large openings of plate 18 to strike plate 19. This is repeated until the gases have passed through plate 24, the proportion of gases passing through the large openings increasing with each plate as the small openings decrease in number. Plates 25 and 26 are only provided with openings 27 as by the time the ings positioned in staggered relation and small. openings decreasing in number toward the outlet end of the casin prevents noise and further prevents bac pressure 5 which would'decrease the power of the engine.
When it is desired to clean the mufller the bolts 31 are removed, the caps taken ofi the casing and after fasteners are removed, the plates taken out. The casing, plates and caps can then be easily and thoroughly cleaned and the mufiler assembled.
What is claimed is caps for said casing provided with passageways, and disks mounted in said casing andv alinement with the large openings of the adjoining plates. I
